  1. 1. Understanding Rt using two-particle correlations by simulating proton-proton collisions in a Monte-Carlo model

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Johan Leygonie; [2021]
    Keywords : QGP; Quark-Gluon-Plasma; Rt; Particle Physics; Proton-proton Collisions; Pythia; Monte-Carlo Model; Bachelor s Thesis; Heavy-ion Collisions; ALICE; CERN; Relative Transverse Activity; Jets; Two-Particles Correlations; Quantum Physics; Physics and Astronomy;

    Abstract : The observable Rt is investigated in the Monte Carlo Model Pythia in order to better understand results from experimental data obtained in the ALICE detector at CERN. The purpose is to reproduce the experiment in a simulation and use the features proposed by Pythia to dig into the unexpected outcomes. READ MORE

  2. 2. Investigation of Autoencoders for Jet Images in Particle Physics

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Partikelfysik

    Author : Jessica Lastow; [2021]
    Keywords : data compression; anomaly detection; jet image; autoencoder; dark matter; machine learning; ATLAS; hadron jet; particle physics; high energy physics; Physics and Astronomy;

    Abstract : Dark matter is an invisible type of matter believed to make up 85 % of the matter in the universe, but it has not yet been identified by experiments. According to certain particle physics theories, possible signatures of dark matter are so-called dark jets. They are the dark matter equivalent to classic jets, i.e collimated streams of particles.

  3. 3. Simulation of Higgs boson pair production in Vector Boson Fusion at the LHC

    University essay from Uppsala universitet/Högenergifysik

    Author : Daniela Romero; [2021]
    Keywords : Higgs boson; vbf; vector boson fusion; high energy physics; lhc; proton collision; madgraph; simulation;

    Abstract : MadGraph5 is used to generate events with Higgs boson pairs from vector boson fusion (VBF) at leading-order (LO) and next-to-leading-order (NLO) accuracy in QCD. The simulations are used to compute fiducial cross-sections in proton-proton collisions at a centre-of-mass energy of 13 TeV, using several kinematic cuts on the outgoing jets, e.g. READ MORE

  4. 4. Searching for Dark Photons with Jet

    University essay from Lunds universitet/Teoretisk partikelfysik

    Author : Ashar Ahmed Kamal; [2020]
    Keywords : light dark matter; jet substructure; Physics and Astronomy;

    Abstract : Dark matter is the greatest mystery of modern particle physics and cosmology. Although an overwhelming amount of observational cosmological evidence has pointed towards a dark sector, only its gravitational effect has been experimentally confirmed. READ MORE

  5. 5. Tests of Autoencoder Compression of Trigger Jets in the ATLAS Experiment

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Erik Wallin; [2020]
    Keywords : Physics and Astronomy;

    Abstract : Limited data storage capability is a large obstacle for saving data in high energy particle physics. One method of partially circumventing these limitations, is trigger level analysis (TLA) as used by the ATLAS experiment. The efficiency of TLA can be further increased by doing effective data compression. READ MORE
